why does boiling water neutralize it?
Boiling water neutralizes it because the high temperature kills bacteria and other microorganisms. The heat from the boiling water denatures the proteins in the microorganisms, which causes them to die. When the microorganisms die, they are no longer able to cause infection. Boiling water is a simple and effective way to neutralize it and make it safe to drink.
how long does it take for water to stop boiling?
Water doesn’t stop boiling. Once it reaches its boiling point, it continues to boil as long as it is being heated. The boiling point of water is the temperature at which its vapor pressure equals the pressure surrounding the liquid and the liquid changes into a vapor. The boiling point of water at sea level is 100 degrees Celsius or 212 degrees Fahrenheit. As water boils, it evaporates, and the steam rises. The steam can be seen as a white cloud above the boiling water. The rate at which water boils depends on several factors, including the temperature of the water, the atmospheric pressure, and the surface area of the water. Boiling water is a common method of cooking food and sterilizing objects.
why does water stop boiling at 100 degrees?
At sea level, water boils at 100 degrees Celsius (212 degrees Fahrenheit). This is because the boiling point of a liquid is the temperature at which its vapor pressure equals the pressure surrounding the liquid and the liquid changes into a vapor. The pressure surrounding the liquid is called the atmospheric pressure.
The atmospheric pressure at sea level is about 101 kilopascals (kPa). This means that the vapor pressure of water at 100 degrees Celsius is also about 101 kPa.
If the pressure surrounding the liquid is increased, the boiling point of the liquid will increase. This is because the increased pressure makes it more difficult for the liquid to vaporize.
Conversely, if the pressure surrounding the liquid is decreased, the boiling point of the liquid will decrease. This is because the decreased pressure makes it easier for the liquid to vaporize.
how do you keep water boiling?
Water boils when its temperature reaches 212 degrees Fahrenheit (100 degrees Celsius) at sea level. To keep water boiling, you need to maintain this temperature by adding heat. This can be done in several ways. One simple way is to keep the pot or kettle on the heat source. If you are using a stove, you can adjust the temperature to maintain a boil. If you are using an electric kettle, it will automatically shut off when the water reaches a boil. Another way to keep water boiling is to add more water. When you add cold water to boiling water, the temperature of the boiling water will drop. To compensate, the heat source will need to increase the temperature of the water to bring it back to a boil. You can also cover the pot or kettle to reduce evaporation. Evaporation can cause the temperature of the boiling water to drop, so covering the pot will help to maintain the temperature.
